Rene had to avenge his loss to Sonia in their previous encounter, but she seemed very motivated to win again. In fact, Rene barely escaped some tight pins by Sonia and was very lucky to slip from under a suffocating facesit-pin. He got lucky with good pins of his own and managed somehow to have more success than Sonia, winning this rematch.
Sonia fought well and was on top more than Rene but he scored more points.
Rene is a good mixed wrestler, hard to pin or submit, but he is not very emotional when fighting females. A guy unlike Waldemar,for example - Waldemar was always aggresive and emotional, furious when losing and satisfied when winning. But rene had time to improve and avenge many of his early losses vs females, like this one

Rene and Sonia had a match a few years ago. Rene was new and not so strong and experienced. She won that match easily. This match is not like the first one.

I've been asking FD to please find a less experienced and strong male that the smaller FD women could be competitive against. I hope it happens.

The info above says that there is arm wrestling and one of pictures shows them arm wrestling. It's not in the video.
